Import Conical Twin-Screw Extruders — Buy in Bulk from Supplier in China

The Conical twin-screw extruders from Blue Ocean International Limited are engineered for profile extrusion of PVC and thermoplastics, with a conical screw geometry optimized for low-shear, high-output applications. The machine features screw diameters of 50mm and 75mm at the feed and discharge ends, a length-to-diameter ratio of 16:1, and a torque capacity of 300 to 900 Nm. It is equipped with a PLC-controlled system with touch-screen interface and three independent heating zones.

The barrel is made from 38CrMoAlA alloy steel with nitride hardening, and the screws are fabricated from high-grade tool steel with corrosion-resistant coatings. The design supports co-rotating, fully intermeshing screws with kneading elements suited for rigid PVC, UPVC, and recycled blends. The extruder can handle feedstock with up to 20% filler content and is calibrated for extrusion speeds of 1 to 8 m/min. Standard output ranges from 100 to 250 kg/h depending on material viscosity and profile geometry.

These extruders are primarily used in the construction industry for manufacturing window frames, door profiles, and decorative cladding.
